>I am very much a newbie to javascript. So I will look up this function; use, upside and downside. One thing I found so far is that javascript is very unforgiving. If I have ANYTHING wrong in my javacript (like, e.g., missing the ending ";") nothing works in the code. And no error appears when I am running it in ASP.NET. I have to be extra careful.

Just to throw one more option at you:
Take a look at Typescript. It's compiles to javascript and is very good at catching errors at that point. Also allows you to define type-safe classes in a C# fashion...
